OneToOneField conflicts with ForeignKey

[kevinastone@…]

I have a model class that has both a OneToOneField and a ForeignKey to the same other class. Eg.

class Base(meta.Model):

name = CharField()

class Extension(meta.Model):

base = meta.OneToOneField(Base)
parent = meta.ForeignKey(Base)

When using Base instance, when I try to call Base.get_extension() it uses the parent foreign key reference instead of the base OneToOne reference.
